Opis:
The concept of legal relationship is a tool that lawyers use to describe the legal situation in which entities find themselves due to applicable legal norms. It is therefore a tool for practical analysis of legal norms. The concept of a legal relationship and other legal concepts related to it are used by a lawyer to determine what rights and obligations a particular entity has in a given legal system in relation to the situation of another entity. In other words, it serves to describe the interdependence of the legal situation of entities due to applicable legal norms. Analysis of the legal relationship and related concepts are also useful for researching the behavior of some entities towards others due to applicable legal norms. The concept of legal relationship and the concepts associated with it are therefore a tool for analyzing law in action, thanks to which it is possible to solve a number of legal problems arising in the practice of applying law. It is important for those branches of law in which there are correlations between legal situations of entities of these branches of law. Therefore, it is also important for the tax law and tax research, in which there are relations between the state and taxpayers and other entities of tax law. Although from the most general point of view the structure of the legal relationship may seem to be very similar, however, legal relations in particular branches of law have their own characteristics. This diversity results from the fact that the content of elements determining specific legal relations in these branches of law is different, such as: the subject of the law, facts causing the creation and termination of the legal relationship as well as the content of the rights and obligations of the parties to this relationship. Research on these elements of the legal relationship allows to achieve specific theoretical and practical goals. Due to the fact that they are embedded in applicable law, they allow to build a model of legal relationship, which becomes a tool for practical analysis of applicable law. Secondly, their study allows to deepen knowledge of the characteristics of individual elements of this relationship, such as the subjects of this right. Thanks to this, it is possible to decide what features an entity should have to be able to become the owner of the rights or obligations of a given branch of law, including tax law. The structure of subjectivity in this branch of law is significantly different from the legal subjectivity of civil law. They also allow to catch the relationships between individual rights and individual rights and obligations regulated in a given branch of law. Finally, they allow to understand the premises that give rise to the rights and obligations incumbent on the subjects of a given branch of law. This in turn allows for an in-depth analysis of the tax law norms themselves, as well as views on individual institutions of this law and their critical analysis, as well as a critical analysis of the views of case law on these legal institutions. In the field of tax law science of various countries, models of a tax law relationship have been already created, which allow ordering and analysis of tax law norms. However, many other countries as the Polish tax law science did not pay much attention to this issue of tax law. Therefore, in many countries the most general model of tax law relationship created by the theory of law is used. The same has happened in Polish tax law science. However, this is an insufficient model, as it requires taking into account the state of tax legislation and the specifics of its regulations. Hence, considerations of tax law doctrine’s sometimes lack consistency due to the lack of an appropriate research tool in the form of a tax law relationship model. They also often conflict with each other, because the starting points for the analyses are different. Therefore, further research on tax law relationship is necessary in this field. This paper presents the assumptions concerning scientific research on developing the concept of a tax law relationship.

Opis:
Earlier experimental studies have demonstrated that: i) Cu,Zn-superoxide dismutase deficiency leads to oxidative stress and carcinogenesis; ii) dysregulation of NF-κB pathway can mediate a wide variety of diseases, including cancer. Therefore, we decided, for the first time, to examine the level of oxidative DNA damage and the DNA binding activity of NF-κB proteins in SOD1 knockout, heterozygous and wild-type mice. Two kinds of biomarkers of oxidatively damaged DNA: urinary excretion of 8-oxodG and 8-oxoGua, and the level of oxidatively damaged DNA were analysed using HPLC-GC-MS and HPLC-EC. The DNA binding activity of p50 and p65 proteins in a nuclear extracts was assessed using NF-κB p50/p65 EZ-TFA transcription factor assay. These parameters were determined in the brain, liver, kidney and urine of SOD1 knockout, heterozygous and wild-type mice. The level of 8-oxodG in DNA was higher in the liver and kidney of knockout mice than in wild type. No differences were found in urinary excretion of 8-oxoGua and 8-oxodG between wild type and the SOD1-deficient animals. The activity of the p50 protein was higher in the kidneys, but surprisingly not in the livers of SOD1-deficient mice, whereas p65 activity did not show any variability. Our results indicate that in Cu,Zn-SOD-deficient animals the level of oxidative DNA damage and NF-κB1 activity are elevated in certain organs only, which may provide some explanation for organ-specific ROS-induced carcinogenesis.

Opis:
Liver transplantation is a well-established treatment of patients with end-stage liver disease and selected liver tumors. Remarkable progress has been made over the last years concerning nearly all of its aspects. The aim of this study was to evaluate the evolution of long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery (Medical University of Warsaw). Material and methods. Data of 1500 liver transplantations performed between 1989 and 2014 were retrospectively analyzed. Transplantations were divided into 3 groups: group 1 including first 500 operations, group 2 including subsequent 500, and group 3 comprising the most recent 500. Five year overall and graft survival were set as outcome measures. Results. Increased number of transplantations performed at the site was associated with increased age of the recipients (p<0.001) and donors (p<0.001), increased rate of male recipients (p<0.001), and increased rate of piggyback operations (p<0.001), and decreased MELD (p<0.001), as well as decreased blood (p=0.006) and plasma (p<0.001) transfusions. Overall survival was 71.6% at 5 years in group 1, 74.5% at 5 years in group 2, and 85% at 2.9 years in group 3 (p=0.008). Improvement of overall survival was particularly observed for primary transplantations (p=0.004). Increased graft survival rates did not reach the level of significance (p=0.136). Conclusions. Long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery are comparable to those achieved in the largest transplant centers worldwide and are continuously improving despite increasing recipient age and wider utilization of organs procured from older donors.

Opis:
The aim of the study was to analyze indications and results of the first one thousand liver transplantations at Chair and Clinic of General, Transplantation and Liver Surgery, Medical University of Warsaw.Material and methods. Data from 1000 transplantations (944 patients) performed at Chair and Clinic of General, Transplantation and Liver Surgery between 1994 and 2011 were analyzed retrospectively. These included 943 first transplantations and 55 retransplantations and 2 re-retransplantations. Frequency of particular indications for first transplantation and retransplantations was established. Perioperative mortality was defined as death within 30 days after the transplantation. Kaplan-Meier survival analysis was used to estimate 5-year patient and graft survival.Results. The most common indications for first transplantation included: liver failure caused by hepatitis C infection (27.8%) and hepatitis B infection (18%) and alcoholic liver disease (17.7%). Early (< 6 months) and late (> 6 months) retransplantations were dominated by hepatic artery thrombosis (54.3%) and recurrence of the underlying disease (45%). Perioperative mortality rate was 8.9% for first transplantations and 34.5% for retransplantations. Five-year patient and graft survival rate was 74.3% and 71%, respectively, after first transplantations and 54.7% and 52.9%, respectively, after retransplantations.Conclusions. Development of liver transplantation program provided more than 1000 transplantations and excellent long-term results. Liver failure caused by hepatitis C and B infections remains the most common cause of liver transplantation and structure of other indications is consistent with European data.
